I have a Nolan modular with Sena. The Sena must be attached using the optional stick-on way of attachment. Works just fine. My Nolan fits my head. The communication system is secondary. But, sena does work with Nolan. My biggest issue is the Nolan will not fit in any compartment of the spyder. But my big ol' fat head needs the biggest outer shell available.... (My wife's tiny pin-head Nolan fits anywhere she wants to put it)
